The following reply was made to PR kern/5995; it has been noted by GNATS. From: daniel@consol.de To: freebsd-gnats-submit@freebsd.org Cc: Subject: Re: kern/5995: System hangs with NFS send error 55 (out of buffer space?) Date: Fri, 13 Mar 1998 17:18:59 +0100 Funny thing happening in this situation: Even if the system doesn't hang completely, the network performance becomes extremely sluggish. Then I decided to ping the machine, or to ping any other machine from it, and what happens is, that rtt's start with ~ 1000ms but decreases by 10 ms for each packet sent!! looks something like this: PING beatles: 64 byte packets 64 bytes from 155.208.6.51: icmp_seq=0. time=1000. ms 64 bytes from 155.208.6.51: icmp_seq=1. time=990. ms 64 bytes from 155.208.6.51: icmp_seq=2. time=980. ms 64 bytes from 155.208.6.51: icmp_seq=3. time=970. ms 64 bytes from 155.208.6.51: icmp_seq=4. time=960. ms 64 bytes from 155.208.6.51: icmp_seq=5. time=950. ms 64 bytes from 155.208.6.51: icmp_seq=6. time=940. ms [..] 64 bytes from 155.208.6.51: icmp_seq=97. time=30. ms 64 bytes from 155.208.6.51: icmp_seq=98. time=20. ms 64 bytes from 155.208.6.51: icmp_seq=99. time=10. ms 64 bytes from 155.208.6.51: icmp_seq=100. time=0. ms 64 bytes from 155.208.6.51: icmp_seq=101. time=1000. ms .. Note that ot starts again from 1000ms after reaching zero. The machines are in a local LAN. I've never seen anything like that before. Comments ?
