Hi,
I have running a Servoy 5.2.16 Application Server on a Debian Virtual Server.
```auto
Operating System Information
os.name=Linux
os.version=2.6.32-042stab078.27
os.arch=i386
java.version=1.6.0_26
```
From time to time (two, three times a month) the Servoy App Server shut down unexpected.
This is what I get in the error log file:
```auto
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (malloc) failed to allocate 32756 bytes for ChunkPool::allocate
# Possible reasons:
# The system is out of physical RAM or swap space
# In 32 bit mode, the process size limit was hit
# Possible solutions:
# Reduce memory load on the system
# Increase physical memory or swap space
# Check if swap backing store is full
# Use 64 bit Java on a 64 bit OS
# Decrease Java heap size (-Xmx/-Xms)
# Decrease number of Java threads
# Decrease Java thread stack sizes (-Xss)
# Set larger code cache with -XX:ReservedCodeCacheSize=
# This output file may be truncated or incomplete.

The Servoy Server settings are:
```auto

```
The Debian Server memory output is:
```auto

```
For me the Debian Server has enough RAM and free memory, or?
Does anybody have an idea?

Thomas

Maybe you need a swap partition.

You are hitting the 32bit memory limit of the OS

Thank you for the reply!
@deezzub
The Hosting company don’t offers Swap partitions for Virtual Server.
@Harjo
You’re right!
I change now to a Dedicated Root Server with a 64 bit OS (Debian) and Swap partition.
