router, mailing lists, memory and suns...

[Scott Ballantyne <sdb@ssr.com>]

It appears that the router can corrupt disks on SunOS 4.1.2 and
probably other SunOS releases. This appears related to memory bloat in
the router when expanding mailing lists.  At one time I believed this
only happened with Rayans zmailer, and I switched to Matti's. While
Matti's has some wonderful improvements, it seems that slowly, over
time the router grows in memory usage until it scribbles all over the
disk.

This is obviously a SunOS bug, but we don't have a maintanence
contract and want to stick with something more BSD-ish than their
latest releases, so I was hoping someone here could suggest something,
or perhaps Matti will be able to track it down.

Here is a ps -auxww after expanding two large (> 1500) lists:


root     26148  2.7  5.0 5508 1144 ?  R    Feb 14  4:38 /usr/local/lib/zmailer/bin/router -dkn 3
root     26147  2.3  5.5 5516 1252 ?  R    Feb 14  4:36 /usr/local/lib/zmailer/bin/router -dkn 3
root     26139  0.0  4.2  888  960 ?  S    Feb 14  2:43 /usr/local/lib/zmailer/bin/router -dkn 3


I now have to kill and restart the router or else spend a morning
restoring disks and listening to user complaints :-(

Thanks for any advice - I wish I had time to debug this myself, but I
am presently overloaded at work.

The router version is 2.99.20.

Thanks again,
sdb
