Possible WebMail problem identified

In our efforts to identify the cause of recent problems with the WebMail server, we have been at a loss for information. We have tried to discover what has been causing the delays and unresponsiveness in WebMail as of late. We have looked at possible memory leaks in daemons, possible attacks, possible miss configurations. All of these have not lead to a clear answer.

It is believed at this point in time that if Ockham’s Razor holds true we may have found the source of the problem. It was discovered late yesterday that the available disk space of the WebMail server was extremely low. Since WebMail serves as an imap gateway temporarily caching and displaying mail messages via a http server, disk space for temporary files is necessary. This has been the best possible explanation for the problems we have seen thus far.

We have increased available disk space on the server. We have also contacted server individuals who reported problems to determine if the issue still persists.

Mail clients reconfigured

The imap and pop3 daemon used by various mail clients to read e-mail messages from the University’s mail server have been reconfigured. The have been assigned to seperate network interfaces.

one interface as been assigned on-campus imap traffic
one interface as been assigned on-campus pop3 traffic
one interface as been assigned off-campus imap & pop3 traffic

These daemons also have been assigned new ssl certificates by the University’s certificate authority.

Modification to CBord backup

This morning there were questions posed by the operators about the status of the ntbackup process on the C-BORD Odyssey server around the location of the backup log file.

During the course of my investigation, I discovered that the use of the %Odyssey% variable does not work in all situations. So I modified the tapebackup.cmd file to use the absolute path contained in the %Odyssey% variable.

SYSLASER1 modification

The HP laserjet 9000 (syslaser1) was tweaked to try and determine source of multiple print jobs. Items changed on printer:

System Setup
Clearable Warnings (changed from Job to On)
Auto Continue (changed from On to Off)

Micros Server Adjustments

The Micros server, which controls the cash registers in the CBORD One-card system, ran out of disk space on the C: drive, causing serveral services to crash. This in turn caused the cash registers to go offline.

The pagefile was split among the C: and D: drives in the folowing manner: 500 MB on C: and 1 GB on D:, and serveral temp files and an old log file were deleted.

The NT backup was moved from 3:30 AM to 2:30 AM, because it was not finishing before opening time for the cafe and diner.
