Hi Vassilis,

Try something like gdb -p `pidof myisamchk` -ex "thr a a bt" and get back to us with
provided output.

Hi,

Debian unstable here with mariadb 11.8.2-1

When I am trying to uncompress a maybe compressed table with parallel-recovers it stalls in around 268KB of TMD file. The original table is 2GB compressed and 3.4GB uncompressed.

For now I remove the --parallel-recover flag.

Any ideas?

root@node00:# ps auxw | grep myisamchk

root     1300496  0.0  0.0 584384  8188 pts/9    Sl+  16:44   0:00 myisamchk --tmpdir=/mnt/bv/db/mysql/../tmp --unpack --force --safe-recover --sort-index --analyze --parallel-recover /mnt/bv/db/mysql/BV/ctgov_paper

root@node00:# strace -p 1300496

strace: Process 1300496 attached
