Interesting space issue

[Jim Howell]

Hi,
	I have an interesting problem.  Over the weekend our syslog forwarder went 
beserk generating over 300,000 messages to about 6 people.  This morning 
our three new Cyrus systems went belly up, (yes that is a technical term), 
actually the master daemon seemed to eventually freeze up.  The only real 
error msgs I can find are these:
Mar 10 00:18:16 postoffice8 lmtpd[27393]: [ID 729713 local6.error] DBERROR: 
opening /opt/cyrus/mailboxes.db: Not enough space
Mar 10 08:04:46 postoffice8 pop3d[2183]: [ID 729713 local6.error] DBERROR: 
opening /opt/cyrus/mailboxes.db: Not enough space
Mar 10 08:12:58 postoffice8 imapd[2489]: [ID 729713 local6.error] DBERROR: 
opening /opt/cyrus/mailboxes.db: Not enough space
Mar 10 08:14:05 postoffice8 imapd[2731]: [ID 729713 local6.error] DBERROR: 
opening /opt/cyrus/mailboxes.db: Not enough space
Mar 10 08:27:59 postoffice8 imapd[3951]: [ID 729713 local6.error] DBERROR: 
opening /opt/cyrus/mailboxes.db: Not enough space

Now I'm been running older versions of Cyrus (1.5.19) for years at 300,000 
messages a day with no trouble.  I don't believe space is really an issue, 
here is a df -k from one of the systems.

This is all with Cyrus 2.1.11 on a V880 with 32GB of memory with Solaris 8 
and, Sendmail 8.12.8.  Anyone seen this before?  Thanks.
