oQueue version 1.9.0 has been released with hopes of addressing Battle.net disconnects.

Changelog:
v1.9.0 UPD: send_xrealm now queue'd with all msg'ing
UPD: oq_ping_user now queue'd with all msg'ing
UPD: increased realm spread from 4 to 7 for wider coverage
UPD: group ad cycle reduced from 30 seconds down to 20 seconds
add: insured oq-checks won't happen more then once every 5 seconds (wow msgs triggering too often)
add: bundled msgs to reduce the quantity of msgs sent between realms

TLDR: oQueue will now send less messages per second, but the messages are now larger in size.
