Are you purging the cache witango cache on that machine using @PURGE?

Hi all,
I've searched the achive of this list but haven't found mention of the problem that I'm seeing:
Our new installation of Witango 5.0.1.065 is giving us trouble on a RedHat 9 box.
The symptom:
the witango daemon (witangod) starts up and serves requests, but after about 5 minutes it just freezes. The tango client eventually times out (after a few minutes) and displays this message:
Client/Plug-in Error
The client encountered problems in communicating with the application server. Please check witangoevents.log for further information.
The witangoevents.log doesn't have anything particularly interesting in it. The last lines look like this:
[10742] 2004-02-02 17:08:20 START INFO Oracle Call Interface (OCI): Enabled [10742] 2004-02-02 17:08:20 START INFO Listener Address: Any [10742] 2004-02-02 17:08:20 START INFO Listener Port: 18100 [10742] 2004-02-02 17:08:20 START INFO Allocated 20 worker threads [10742] 2004-02-02 17:08:21 RUNTIME INFO Skipping empty startup URL [10742] 2004-02-02 17:08:22 RUNTIME INFO Started accepting user requests
We're using an apache2 built from source. Have tried the recommended version 2.0.46 as well as the current release (2.0.48). We're seeing the same problem with both versions of apache.
An strace of the catatonic witangod process shows me this sort of thing over and over:
gettimeofday({1075922257, 962880}, NULL) = 0 gettimeofday({1075922257, 963070}, NULL) = 0 futex(0x82d2964, FUTEX_WAIT, 150248, {0, 999810000}) = -1 ETIMEDOUT (Connection timed out) gettimeofday({1075922258, 972906}, NULL) = 0 gettimeofday({1075922258, 973101}, NULL) = 0 futex(0x82d2964, FUTEX_WAIT, 150249, {0, 999805000}) = -1 ETIMEDOUT (Connection timed out)
Although an strace of a functioning witangod process looks much the same. I think that just tells me that strace isn't seeing witangod's threads very well.
Restarting the witango daemon fixes the problem for another 5 minutes or so.
Anyone else out there seen this sort of problem?
