Hello,
If you are using a Linux system for PDL or EIDS clients, you should check that they are okay.
On several RedHat Enterprise Linux 6 servers, PDL and EIDS client usage was above 100% and causing performance problems. This started when a leap second was added on June 30th.
Here is an open bug describing the problem in more detail:
https://bugzilla.redhat.com/show_bug.cgi?id=836748
You can check whether your system is affected by running "top", checking the %CPU (and/or load average):
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
3324 pdl 20 0 14.8g 201m 10m S 889.7 0.5 52006:16 java
A system restart should resolve the issue temporarily (until the next leap second), and you should plan to update the kernel when a patch is available.
Thanks,
Jeremy
