Symptoms

Customer running single server deployment on Linux RedHat6.

OHS web server, AOM components and mainwin components were terminated, all referring to Operating system error 11 in some way.

The behavior is intermittent, and which process is terminated is random.

OS code 11 (EAGAIN) means: Resource temporarily unavailable

The following error messages could be observed:

a) Siebel Server: (schedule.cpp (480) err=1376294 sys=11) SBL-SMI-00038: Internal: Cannot create process for siebmtshw

b) OHS:  [OHS] [INCIDENT_ERROR:20] [OHS-9999] [core.c] [pid: 21121] [tid: 125913968] [user: root] [VirtualHost: main] (11)Resource temporarily unavailable:  apr_thread_create: unable to create worker thread

c) when attaching with strace to regss mainwin process: clone() system call retuns EAGAIN

d) AOM crashing in the dispatcher thread that is responsible to create new threads
