Lock problem with mupdate

[Frank Elsner]

Hi experts,

we have a mupdate server (Solaris 10, Cyrus 2.3.16) and frontnend and backend
servers (Redhat Linux due to migration from Solaris environment).

The RHEL frontend connects to the (Solaris) mupdate server, authentication
work. 

But after 

Apr 17 07:27:21 eg-mailfrontend cyrus/mupdate[7395]: successful mupdate connection to mupdate-febe.intern.tu-berlin.de
Apr 17 07:27:21 eg-mailfrontend cyrus/mupdate[7395]: scarfing mailbox list from master mupdate server

nothing happens, the mailbox list lacks update.

Lets look what mupdate does:

[root at eg-mailfrontend elsnccpa]# ps -ef | grep mupdate | grep -v grep
cyrus     7393  7388  0 07:27 ?        00:00:00 mupdate
cyrus     7395  7388  0 07:27 ?        00:00:00 mupdate
[root at eg-mailfrontend elsnccpa]# strace -p 7396
Process 7396 attached - interrupt to quit
accept(4, ^C <unfinished ...>
Process 7396 detached
[root at eg-mailfrontend elsnccpa]# man tcpdump
[root at eg-mailfrontend elsnccpa]# man imapd.conf
[root at eg-mailfrontend elsnccpa]# man imapd.conf
[root at eg-mailfrontend elsnccpa]# strace -p 7395
Process 7395 attached - interrupt to quit
futex(0x7f8af2249e84, FUTEX_WAIT_PRIVATE, 1, NULL^C <unfinished ...>

The frontends running the same cyrus version under Solaris work perfect.

Any clue?
