I thought that was what the openafs-debuginfo-1.4.2 package delivered. Will
rebuild.

Summary : Debug information for package openafs
Description :
This package provides debug information for package openafs.
Debug information is useful when developing applications that use this
package or when debugging this package.
The fact that your servers on another subnet are having no issues makes

The clients can not access a volume on these servers at this time but
recover as soon as server is restarted. The disk io is almost none existent
at the time of the problem and load/cpu usage are low. If I knwo what I need
to collect the servers are dying almost every night so I should be able to
get something more useful.
Cheers
