Possibly try increasing mail_process_size. It defaults to 256 and I had to raise it to 1024 (1024 megs) to allow some squat searches to complete. I also have 4G of ram. You can also try watching the process in top to see how large it grows before it dies as a clue to what limit it is hitting.

I tried to use squat index, but got error:

It is strange because this server has 4 Gb or RAM.

some lines from dovecot -n

IMHO it will be better to write in log requested memory size: src/lib/mempool-system.c:

• "pool_system_realloc(): Out of memory");

• "pool_system_realloc(): Out of memory, when realloc to %"PRIuSIZE_T" bytes", new_size);
