OSA control panel is down displaying Service is temporary unavailable message

java process cannot start:

[root@poaui ~]# java
Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.


Virtuozzo container where UI service resides reached UBC resource limits, for example:

[root@poaui ~]# cat /proc/user_beancounters
Version: 2.5
uid  resource     held       maxheld      barrier                limit              failcnt
numtcpsock    80              80           80                   80                  11030


Closely check output of cat /proc/user_beancounters command comparing maxheld and barrier columns.

Increase limits reached barrier or close to:

misclin01 ~ # vzctl set 1002 --numtcpsock 800 --save
UBC limits were set successfully
Saved parameters for Container 1002

Where 1002 is a Virtozzo container ID
