sort stage issue

Post by **admin** » Thu Oct 23, 2003 11:36 pm

Hi, All
I have a job using sort stage, it runs well many times. However, it always
issued a error message today as below :

SORT: ds_ipcgetnext - timeout waiting for mutex

and stopped at sort stage processing.

Can anybody tell me what this problem is ? how to fix it ?
Many thanks in advance

There is a known issue with mutex locks on HP-UX. Search the archives (now at www.dsxchange.com) to find it. And the workaround. It's related to the SPINTRIES and SPINSLEEP configuration parameters; to quote one of the Ascential support people, the machine spins too fast for its own good! These configurable parameters were added specifically to address this issue.

Problems with mutex locks have also been encountered, though less frequently, on AIX, by DataStage users.
