Job failing with 'ds_ipcput() - timeout waiting for mutex'

Hi,

We have a Server job in DS 8.5 that uses multiple hash files for lookup , this job throws 'ds_ipcput() - timeout waiting for mutex' error when it runs in parallel with some other jobs. While the same job finishes successfully when ran individually.

I have searched the forum for the error message but could not find any solution, can some one please help on this.

We used to face this issue on a regular basis. The fix that worked for us was - reducing the number of DS jobs that run concurrently. Hope this helps.

What kind of UNIX? There are environment variables where you can tune the SPINSLEEP and SPINTRIES for mutex locks available for some UNIX platforms. But, as noted, ultimately the wait times being experienced, due to load, are longer than the smart semaphores (mutex locks) are tuned for.
