Yes! Everything works fine now! Except one thing, hm ...:
I want to use Spread to send cache expiry messages to a bunch of machines. These
messages are quite short char strings (actually the object id's).
I'm using SP_multicast like this:
my $rc = SP_multicast($self->{mbox}, SAFE_MESS, @{$self->{joined_groups}}, 0,
"$identifier") || warn "Cannot multicast to group: $sperrno, $!";
This is ok as far as I do not send more than about 1600 messages in a short time
(about 2-5 secs). After that SP_multicast starts to complain:
"Cannot multicast to group: Illegal Session, Datenübergabe unterbrochen (broken
pipe) at blib/lib/Urbia/Base/Cache.pm line 90."
Seems like there is a buffer running out of memory... But I couldn't find any
hints in the documentation on how much data Spread can buffer in the mailbox.
Or maybe SAFE_MESS is not the right mode for this application?
Any idea?
