dovecot - Mar 2007 - lock file on embedded device

Hi.

That's my first post. it's driving me crazy.

I'm trying to get dovecot working with vpopmail on Openwrt, an embedded
linux-like OS for some routers . So actually my aim looks like get dovecot
working with little hardware resources (32 MB of Ram, 8 MB of disk mem.)

I've cross compiled it well(it looks like).

the login against vpopmail works.

using mmap it cannot even select the inbox, the log says:

 Error: IMAP(test at fabri-fibra.org): file_dotlock_create() failed with file
/home/vpopmail/domains/mydomain.org/test/Maildir/dovecot.index.log: No such file
or directory

And an impressive Kernel page fault:
 
Mar 21 17:38:48 (none) kern.alert kernel: Unable to handle kernel paging request
at virtual address 00000008, epc == 8004cce8, ra == 8004cc34
Mar 21 17:38:48 (none) kern.warn kernel: Oops in fault.c::do_page_fault, line
206:

etc etc... even this error: Mar 21 17:38:48 (none) kern.crit kernel: ASSERTION
FAILED: file->f_dentry != NULL at aux.c:120 (check_mini_fo_file)

With mmap disabled i can select the inbox and read/write just the first time
since  any new attempt get stucked because the file dovecot-uidlist.lock was not
removed.

more details:
dovecot: Mar 21 17:13:34 Warning: IMAP(test at fabri-fibra.org): Our dotlock
file /home/vpopmail/domains/mydomain.org/test/Maildir/dovecot-uidlist.lock was
overridden
(kept it 0 secs) 


By the way my file system is a jffs, and my disk has 500K left.

I will appreciate any tips.

Fabrizio.

See if dotlock_use_excl=yes helps anything.

Don't do this.

Really, a device with 500k free disk space and no swap is no place to 
be running an IMAP server. A system using flash memory for "disk" is 
not suitable as a mail store, because that is a write-intensive 
application and you will wear out the flash.

thanks for the suggest. That's just an attempt.I will install everything on
a device with usb support, therefore i will be able to use an hard disk or
something like that.
