>Description:
When installing php 5.2.0 I got a lot of messages swap_pager: indefinite wait buffer: bufobj: 0, blkno: 1234, size 4096. The system was unresposive, it was a deadlock, I had to shut it down manually.
The output of swapinfo:
Device 1K-blocks Used Avail Capacity
/dev/ad1s1b 105424 28 105424 0%
/dev/md0 131072 16 131072 0%
Total 236496 44 236452 0%
Interesting info from dmesg.boot:
real memory = 100663296 (96 MB)
avail memory = 93147136 (88 MB) (why only 88?)
When the kernel was compiled, I had 64 Mb RAM, then I have added 32 more RAM.
I saw that this problem also exists with the 6.1R. The system also crashed a lot of times when I tried to portupgrade mysql4.1 (the system doesn't use any jails or something to blame on)
