Re: [Linux-cluster] dlm_sendd 100% CPU



Someone reported earlier a similar problem with dlm_sendd taking up 100%:

http://www.mail-archive.com/linux-cluster redhat com/msg01002.html

Could our problem be with bugs in our kernel and GFS versions ? (2.6.9- X) ?



Any ideas why dlm_sendd is taking up 100% CPU ?

We have this intermittent problem which seems to happen when a group of users log into our servers at the same time, possibly opening/ writing files from the same mount point.

Should dlm_sendd ever take up 100% of the CPU ?

Any help would be greatly appreciated.... i mean greatly.... like sell my soul "greatly". If there is any additional diagnostic info i can provide, please let me know. /var/log/messages just shows failed SMB pipes/write failures due to the high load/lockups.
