After a couple of hours, I get more and more processes in "COM" state and only a shutdown and restart helps.
The error log shows a couple of messages like
[Thu Jun 14 19:59:06 2007] [error] (6)no such device or address: error assigning
channel to control mailbox APACHE$SWS_CONTROL_MBX_5\n
Google was no help.
Any Ideas?
Dieter

Re: CSWS 2.1 hangs
VMS 8.3 allows mailbox unit numbers above 32767. We had one application "break" because of this.
Check the value of the APACHE$*_CONTROL_MBX logical name periodically. You may be able to verify whether or not CSWS can handle mailbox unit numbers above 32767.
We logged a call last winter on this and got a patch for the mailbox driver from VMS Engineering. I don't think the patch has been released in an official ECO as of yet.

Re: CSWS 2.1 hangs
I thought I should check the versions of CSWS we are running as we may run into the same problem in September when we will complete our VMS 8.3 upgrades. We have not upgraded any of our clusters that run CSWS yet.
We are running CSWS 2.1-1 on VMS 8.2. I checked the CSWS website and found that there is an update to 2.1-1 that fixes two problems, one of which is described as:
Zero-length files cause server processes to become CPU-bound and hang.
Could this be your problem? Are you running the 2.1 or 2.1-1 with or without Update 01?

Re: CSWS 2.1 hangs
Thank your for your help. Update was installed but not active. Apache$shutdown does not (at least on my system) remove the installed images. An $ Image remove on all apache stuff, a $deassign/system/exec on some apache logicals an a apache$restart and here we go: good performance, stable apache processes.
Thanks again
Dieter
