Weekly log #81 for week ending 10-04-1996

Continued fire fighting in the aftermath of the VMS upgrade.
Installed an operating system patch on Bigone to deal with a bug in the queue manager that caused one of its data files to grow excessively and consume disk space.
Set Tejon so that outgoing alarm email will have a return address pointing back to Bigone. This will prevent automatic mail replies from going to the on-line system.
Set up NFS between Tejon and Bigone for use by the Cull process. This worked for a while and then died. We are investigating this problem.

Weekly log #82 for week ending 10-11-1996

Rebooted Bigone and its satellites to finish installing the queue manager patch and to adjust system tuning parameters.
Found the problem with Cull and NFS. The NFS server is not closing channels to phantom files on Tejon. After a time, the server process crashes when it exceeds the allowed number of open file channels. We are investigating what can be done to correct this.
Kate could not log on to her workstation. Allan was able to fix this by removing some logical definitions from her login.com file.
There was a problem with the SCEC jukebox disks that are NFS mounted on Bigone. UCX NFS works differently from the Multinet NFS that we used before.
Fixed a problem with anonymous FTP access to Bigone for Menlo Park. This is another thing that was broken by the upgrade.

Installed UCX version 4.0 on Bbear so that Cull can run there. Also this was to test the theory that our problems with NFS were caused by incompatibility between UCX 3.3 and 4.0. This turned out not to be the case, as the problem is still occurring. We are continuing to investigate.
Changed the NFS parameters for mounting the scec jukebox to fix a problem that Katrin reported.
One of the tape drives that Tejon used for Squirrel failed. We swapped it for the drive that was on Malibu. The failed drive worked for nightly backups when it was put back on Malibu. It seems to have some mechanical problems, but backup is less time-sensitive than Squirrel, so the drive was able to work.
Attended the GPS computer users meeting.
Fixed an automated FTP script for Fred Klein in Menlo Park.

Installed the new HP JetDirect ethernet print server for testing. Got it configured and did some test printing with it.
Dave Wald's new workstation has been having apparent network problems. These problems seem to be connected in some way to either the network or the electrical system in the Tan house. Testing is continuing.
Rebuilt the UCX POP server for Eudora mail. The old server had been dying from time to time. Installing an updated C compiler and rebuilding the server executable seemed to fix the problem.
Traced the 'insufficient dynamic memory' error message to a system tuning parameter that needed to be increased. Rebooted Bigone and satellites to adjust this.
