Hi guys,
I’m trying to deploy an update to my solution for about an hour. Put the server also on maintenance but still the deploy won’t end. Right now after I put the server on maintenance I’m waiting for 15 minites with same screen:
Importing AeroPlus 03.servoy...
[info] Import contains XML version 15 and repository version 38.
I just can’t wait 15 minutes to upload and in this time clients can’t connect. And it seems to never ends. I just can’t wait. I have to stop it now.
Is the servoy_server in a local network or are you connected over the internet?
Check the connection quality and speed. Also between servoy_server and sql_server, if on different machines.
Is anything running on the servermachine occuring a system utilisation?
Try a clean install/update of your solution by deleting the old version(s), restart the servoy_server… or better restart (if possible) the server machine.
Perhaps you should create a new export file of your solution.
Hope this helps
Thomas
Hi Bogdan,
So it’s importing so this means the .servoy has been uploaded and Servoy server has been processing it.
What backend database do you use for the repository ?
Can you check if you see any queries waiting on locks using a DBA tool (for PostgreSQL use pgAdmin > menubar > Tools > Server Status )
Also do you see any load on the Servoy process and/or the database process ?
Hi, thanks! I’ll check next time. Right now I’m afraid to give it another try. There are users inside and I don’t want to make them wait as before.
I finally manage to upload after restarting the server couple of times. Once it crashed, then it worked. And it took only 3 - 5 minutes.
Crashed ? The Servoy server process just quit ? Got a crashlog ?
Yes, it crashed. I have a topic on this: https://forum.servoy.com/viewtopic.php?f=5&t=17025
The heap is OK, but the memory used by java is mad.

I need to get it run online on another server, too see if it behaves the same, but I want to keep the same database, and eventually make it work with more servoy servers and load balancing, but still didn’t figure out how to do some stuff. For this I have this topic open: viewtopic.php?f=5&t=16965
I see that you answered me there. I will post there some more stuff I tried about the db sequences and db identities. And I also have the users problem I mentioned there.
Thanks.
Hi Bogdan,
are you using some kind of VPS ? or Linux kernel virtualization?
We have seen such strange memory error’s also deploying java apps on VPS’ses
Hello, it’s a Debian. I don’t know how it’s installed. I know only it’s a vps. From what I remember the problem appeared after the kernel was updated. But I also have another java server app running there that runs fine even after the kernel update.
So I really need to get it run on another vps, but I want to keep the database here, because it runs fine. and eventually to install another servoy as backup. So I really need to have at least 2 servers running with only one database to avoid situations like this. We are online and each time the server crashes we risk to loose the users.
try to follow one (use 64 bit) or the other instructions the error tells you to do:
Hi,
I tried those things, but the situation is the same. In the end the java memory it’s still too much, approaching 2GB at startup and then in 1 - 2 days it goes even more.
Can someone please answer me to this topic: viewtopic.php?f=5&t=16965
I really need to install another instance of servoy on another vps, but I want to use the same database, which runs ok. And also to keep the current server instance although it has these problems. But at least it runs and people can use it.
Thanks,
Bogdan.
Hi Bogdan,
I have also running two different solutions on two debian 5 virtual servers without problems. This are the Server Info:
JVM Information
java.vm.name=Java HotSpot(TM) Server VM
java.version=1.6.0_22
java.vm.info=mixed mode
java.vm.vendor=Sun Microsystems Inc.
Operating System Information

os.version=2.6.18-028stab091.2

None Heap memory: allocated=43168K, used=42672K, max=573440K
Your java version is newer than on my servers. Maybe an earlier version could fix your problem?
Although I have set the max heap memory to 2 GB, the Sytem Information returns only the 699072K. I don’t know why? The Server has enough RAM (4 GB).

Hello Thomas,
Can you please tell me how much memory java use? Also my heap memory seems OK.

Hi Bogdan,
I get this if I execute ps -aux for running services:
admin 12015 0.0 0.0 4256 1100 ? S Sep14 0:00 /bin/sh ./servoy_server.sh
admin 28005 0.0 3.6 1453636 230824 ? Sl Oct26 8:41 java -Djava.awt.headless=true -Xmx7
and this is my setting in the servoy_server.sh file:
java -Djava.awt.headless=true -Xmx1280m -Xms256m -XX:MaxPermSize=1024m
I hope this helps
Thomas
That’s great! I wish I would have that.
Can no one answer me to this topic: viewtopic.php?f=5&t=16965 ? Please! I really need to install another servoy, but I want to keep the database and the current servoy.
