Comment (by ttcoder):
Doing ticket archeology, I see that #5228 #5242 #5544 #5919 have all been
closed after VM fixes ; similar message, but different backtrace (vm
instead of file_cache)
Stuff also happens when Tuneprepper fork()s : #12518 #12408 (but we're no
longer selling that app, so could close those tickets as invalid).
Recent active tickets are #13274, and especially #13205 (that latter one
is in {{{file_cache_write()}}}, so closest to this ticket?)
Notes to self:
- this occurs with hrev53894.. Upgrade this station (at least) to beta2
when it's out ? I see there's been some fixes done to the file cache
recently. And refrain from doing backups in the meantime. Not much longer
to wait anyway.
- if this still occurs with beta2, ping this ticket to get it looked into
in a few weeks ?
- that stations also has BFS errors reported in syslog, but seems
unrelated to the KDL since other KDL tickets listed above don't seem to
have BFS errors. Anyway here they are:
{{{
bfs: InitCheck:325: Bad data
bfs: inode at 2099031 is already deleted!
bfs: GetNextMatching:615: Bad data
bfs: could not get inode 2099031 in index "size"!
bfs: InitCheck:325: Bad data
bfs: inode at 2099032 is already deleted!
bfs: GetNextMatching:615: Bad data
bfs: could not get inode 2099032 in index "size"!
}}}
This one is hidden among unrelated logs, spotted it by chance:
{{{
2020-05-28 09:43:44 KERN: bfs: volume reports 49876469 used blocks,
correct is 49509747
}}}
(typical Haiku syslogging : important information written in all-
lowercase, hidden in a ocean of noisy informational reporting *g*)
