Hi,While troubleshooting an other network issue, I enabled the netstats.py module to report "udp_rcvbufrerrors".
Ironically, it seems to me as if gmond itself is experiencing udp receive buffer errors.
When I check out /proc/net/udp for drops, amongst other things I see:sl local_address rem_address st tx_queue rx_queue tr tm->when retrnsmt uid timeout inode ref pointer drops 51: 00000000:21DD 00000000:0000 07 00000000:00000000 00:00000000 00000000 103 0 72590718 2 ffff8803a1a5d140 6676
It shows a 6676 dropcount for a socket with uid: 103
When I check out which process has this uid, it is gmond:
# ps -ef n | grep '103 '
103 7800 1 0 10:32 ? Ssl 0:04 /usr/sbin/gmond
I have tried tweaking some sysctl settings, increasing rmem for udp and
increasing the max_udp_message_len in gmond.conf but there seems to be
no effect.
Is this possibly a bug, or am I missing something and doing it wrong? ;) Cheers, - Ramon. -- ing. R.
