-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
I have encountered a strange issue in 2.6.0 and 2.6.1
I run a PGP Public key server on this machine and under 2.4.x it's
"smooth as silk". But if I boot under 2.6.x, it's gaurenteed failure. If
I try to build a database using the build command (this is an sks
server, so it's sks build or sks fastbuild) I IMMEDIATELY get Bdb
error. But the exact same command with the exact same libraries and
input files under 2.4.20 works without a hitch.
Anyone got any ideas? Anything else I can provide to assist in debugging?

this might be the same issue that hit some rpm versions; some versions
of db4 seem to detect the O_DIRECT header presence and starts using
O_DIRECT, without honoring the alignment requirements linux puts on
O_DIRECT usage...

Off the top of my head, O_DIRECT horkage? I believe that 2.6 has more
stringent buffer alignment requirements. A quick 'strace' would probably show
if that's the problem.

On top of what file system berkdb is created? I have a reminiscence that
Sleepy Cat used to have a problem with reiserfs, due to large
stat->st_blksize value. Oleg do you remember this?

No, that problem was different. And it was believed that BErkeley DB might just
be performing a bit slower on reiserfs, though I never was able to reproduce and
Sleepycat's code contains it own limit on maximal block size (it uses 16k
blocksize if on suggested by FS is bigger that 16k).
Definitely there were no crashes.
Bye,
Oleg
