[Dovecot] Out of memory after upgrading to dovecot 2.0.21

[Arnaud Abélard]

Hello,

I've upgraded our servers and now dovecot seems to be running out of 
memory when accessing my own mailbox (and only mine, which is in a way 
pretty fortunate):

dovecot: imap(abelard-a): Error: mmap() failed with file 
/vmail/a/b/abelard-a/dovecot.index.cache: Cannot allocate memory

imap(abelard-a): Fatal: pool_system_realloc(131072): Out of memory

/vmail/a/b/abelard-a/dovecot.index.cache is 224MB big and my mailbox is 
72% full of 8GB.

any idea of what is happening?

Thanks in advance,

Arnaud
