Re: 2.1.128 Lock

A very similar thing happened to me, running stock 2.1.128. I was
compiling Mozilla when "make" seemed to suddenly hang and do nothing...I
tried to spawn a new rxvt to login to see what was happening, and it
didn't pop up. I tried a few more times and nothing came up. I switched
to console where I had an irc session running...I could still type and
everything seemed to be okay, but when I tried to login to a console it
took about 10 seconds before spitting out the "uptime" and then another 10
seconds or so before giving me a prompt. During this time the disk was
almost unused. This looks like exactly what happened with 2.1.127ac1 when
I put it on the mail server machine after 10 minutes of uptime (heavy
load). The number of new running processes kept rising and rising (POP3
logins), and new processes seemed "blocked" (although nothing was shown as
blocked in "vmstat" which was running at the time). I rebooted the
mail server because it needed to be up _asap_, but my machine at home here
which just the problem seemed to fix itself after about 30 seconds.

Machine has 128MB SDRAM, K6 233, ASUS TX97 board. Compiled with GCC
2.7.2.3. 3 EIDE drives, but the mail server I described earlier had a 5
SCSI drives.
