audit collector connect fails

My sender fails to connect to my collector.

Is there any reason a MLS-policy F9 audisp-remote should be unable to
connect to a targeted-policy F9 auditd? I have no ipsec or anything else
involved...

I am looking for some hint as to why the connection is failing but I see
only this on the sender:

- lsof says I'm stuck on SYN_SENT
TCP comms:38827->192.168.30.120:tsdos390 (SYN_SENT)

- audit search on sender
ausearch -ts today -i -c audisp-remote:
...
----
type=SYSCALL msg=audit(09/11/2008 16:14:45.102:19013) : arch=x86_64

subj=system_u:system_r:audisp_remote_t:s15:c0.c1023 key=(null)

Same audit versions on each (1.7.5-1).

On the sender, I can do a "newrole -l SystemHigh" and connect via
"telnet <collector> 1237", so I don't think it is the level giving me
any grief - sender is in permissive mode so there are AVCs but it should
work.

Eventually on the sender I get this:
Sep 11 16:57:12 comms audisp-remote: Error connecting to 192.168.30.120: Connection timed out - exiting
Sep 11 16:57:14 comms audispd: plugin /sbin/audisp-remote terminated unexpectedly

On the collector machine I see the listen socket open but I see no
denials in the messages log or the audit log.

Any suggestions?

Thx,
