Hi Joe,
I've implemented the logging tweaks, however it only stopped after I
restarted both clusters and the DAS, but this is probably a known issue.
I'd like to send you some log files but the question is will it be helpfull
as I can't seem to find the logfile containing the start of the problem,
we've been deleting them from time to time... so only got about 2GB of logs
of the past 2 days. I could re-enable logging but if this requires me to
bring down the cluster it will take some time as we're not fond of bringing
down a live system during business hours.
Regarding your other suggestions, yes we are on Linux (ubuntu), but we're on
beefy machines with 8 CPUs and a 24GB RAM, so the machines are hardly used
for the moment, 0.40 loadavg.
# cat /proc/sys/net/core/rmem_max
131071
# cat /proc/sys/net/core/rmem_default
124928
Our UDP buffers might need tuning for heavyer loads, which I expect in the
future with other apps deployed, but I would not expect the current load to
require larger buffersizes, but I'm no expert in this area so I could be
wrong here.
Thanks for your assistance.
