(https://confluence.atlassian.com/display/JIRAKB/OutOfMemory+Errors+Due+to+Running+Out+of+Native+Thread+Limitation ) says caused by RESTLET ,but i can't find any log contain "
(https://confluence.atlassian.com/display/FISHKB/Fix+Out+of+Memory+errors+by+increasing+available+memory#FixOutofMemoryerrorsbyincreasingavailablememory-OutOfMemoryError:unabletocreatenewnativethread) says it may caused by the size of the stack per thread

This is indeed a strange issue because if you were running a 32bit JVM this issue would be more understandable, but you appear to have a fully provisioned server and your instance is running on a 64bit JVM, which means we're going to need to dig a bit deeper into this issue to understand what is happening here. So, can I ask you to open a ticket with Support, including a copy of your logs, so that we can dig deeper into what is happening here?
All the best,
Maximum memory pool to 1GB = increase that to 2Gb. I suppose you're talking about the heap (-Xmx)
How many threads are configured per container ? It is the default (150) ? If not, you may carefully want to lower this number. Windows has no official limit on threads, but over 1024 threads per process behaves very bad. If you accidentaly changed this to a very high number it can also explain it.

1. sorry of my poor knowledge of thread and process ,can you tell me how to get many threads per progress in the server?
2. do i also have to set size of the stack per thread to 512k ?
