Memory high by java process

[Mohamad Suhairi Abdul Halim]

Hi

We encounter and major alarm for our UMP server, due to memory high for java process. the memory high maintain to 80% and nearly touch to critical threshold.

are this memory high due to wasp probe java setting : max_perm_size?

our max_perm_size = 1024m

if i double the java size can its eliminate the java high memory cause?

[Gene Howard]

the UMP is configured with the following parameters for memory:
<opt>
java_mem_max = -Xmx4g
java_mem_init = -Xms512m
max_perm_size = -XX:MaxPermSize=512m
</opt>

The java_mem_max should limit the memory for the probe.
the default is 1024 which is not high enough for anything but a small lab or test environment.
for production, this should be a minimum of 6gigs.

Please see the sizing guide below:

Please provide more details on the server specifications, all the ump memory parameters, UIM version, and the number of expected concurrent users for us to be able to provide more information or help

​Hi Howard,

Here is my wasp  probe setting that I capture from our UMP server

java_mem_init = -Xms8192m
max_perm_size = -XX:MaxPermSize = 1024m


User concurrent: 100++

Windows server 2012 r2  Standard 64bit

RAM : 32 GB
