PostgreSQL version: 8.4.11
Operating system: CentOS 6.0 - 2.6.32-220.13.1.el6.x86_64
Description:
Primarily checked on PG 8.4.9 (same OS), problem also occurs. Few times a
day I get a situation where PostgreSQL stops running for 1-2 minutes. CPU is
running 99% in systime. IO is OK, only interrupts are extremely high (over
100k). System operates on 2 x Xeon 10 Core, 128 GB RAM, raid 10. Does anyone
have any idea?
