I had encountered a typical scenario, we have TransmitIdle enabled for the groups and due to an extended link issue all the groups went into TransIdle state ( except a few, which went into suspended ).

The snow cache was set to 94% ( default ) and the overall cache consumption by srdf/a was 64%. As other applications in the DMX-4 was starting to get affected specially the BCV syncs .. etc , i had to suspend all the RDF groups with a "suspend -immediate" to prevent the capture cycles from accumulating into the cache.

Cache Size (Mirrored) is  163840 (MB).

I didn't get a chance to analyze the situation of why some groups were in TransIdle and some were suspended as i had to prevent the production stuffs from being affected. But still wondering why it happened.

Anyone can throw some light on this one ?
