Symptoms

Every 3-4 days PBA-S Container is highly loaded, login to PBA-S panels is not possible.

Cause

The following errors are shown in the system log (/var/log/messages) on HW node where PBA-S container resides:

Dec 11 11:52:13 manage kernel: [18853220.233798] TCP: too many of orphaned sockets (100 in CT90)

Where CT90 is ID of PBA-S container, HW node is Parallels Virtuozzo Containers 4.7.

The error above was considered to be a kernel bug according to this forum thread:

TCP: too many of orphaned sockets
