[Dovecot] failed: Cannot allocate memory

Hi

when I try to index messages using squat on a 26'000 emails mailbox I 
get the below errors at the point dovecot says "* OK Mailbox indexing 
finished".

2010-01-30 08:12:50 sleipnir local7.err dovecot  IMAP(s...@dom.com): 
read(/var/tmp/dovecot/spam/indexes/.INBOX_score20/dovecot.index.search.uids)

This is the configuration I use for squat:

fts = squat
fts_squat = partial=4 full=10

Dovecot version is 1.2.10, patched with sieve.

Thanks for any answers,

best,
