-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi again!
I've seen the other thread about lost connections, but my trace is different (the full file is attached):
09:02:24.139525 IP 192.168.18.34.7001 > 192.168.18.2.7000: rx data fs call op#222605814 (44) 09:02:24.918195 IP 192.168.18.34.7001 > 192.168.18.2.7000: rx data fs call op#222605814 (44) 09:02:25.938094 IP 192.168.18.34.7001 > 192.168.18.2.7000: rx data fs call op#222605814 (44) 09:02:27.139930 IP 192.168.18.2.7000 > 192.168.18.34.7001: rx abort (32) 09:02:27.467971 IP 192.168.18.34.7001 > 192.168.18.2.7000: rx data fs call op#222605814 (44) 09:02:29.507820 IP 192.168.18.34.7001 > 192.168.18.2.7000: rx ack first 1 serial 0 reason ping (65) 09:02:30.017763 IP 192.168.18.34.7001 > 192.168.18.2.7000: rx data fs call op#222605814 (44) 09:02:30.458831 IP 192.168.18.2.7000 > 192.168.18.34.7001: rx abort (32)The problem seems to have been correctly described by Lyle in the other thread, so what can we do about it? I'm running 1.3.81 server and clients, but I can of course upgrade if that fixes this bug. Server and client are Dual-Opteron, running i686 kernel and userspace from Debian Sarge (no time for amd64 upgrade yet).
As a side note: this happens only during continuous traffic (compute cluster analyzing some TB of experiment data), not on the desktop nodes, where the traffic is not so sustained and high volume.

The only immediate fix I have found is to stop/restart the openafs-client (Debian sarge, 1.3.81, on clients and servers). What can I do to further debug the cause of this? The problem is that this phenomenon eats batch jobs by the hundreds.-server version? -abort error code?-better yet,tcpdump with 1500 byte packet capture size during the window it fails?_______________________________________________ OpenAFS-devel mailing list [email protected] https://lists.openafs.org/mailman/listinfo/openafs-devel
