TsooRad is a blog for John Weber. John is a Skype for Business MVP (2015-2016) - before that, a Lync Server MVP (2010-2014). My day job is titled "Technical Lead, MS UC" - I work with an awesome group of people at CDW, LLC. I’ve been at this gig in one fashion or another since 1988 - starting with desktops (remember Z-248’s?) and now I am in Portland, Oregon. I focus on collaboration and infrastructure. This means Exchange of all flavors, Skype, LCS/OCS/Lync, Windows, business process, and learning new stuff. I have a variety of interests - some of which may rear their ugly head in this forum. I have a variety of certifications dating back to Novell CNE and working up through the Microsoft MCP stack to MCITP multiple times. FWIW, I am on my third career - ex-USMC, retired US Army. I have a fancy MBA. One of these days, I intend to start teaching. The opinions expressed on this blog are mine and mine alone.

SfB Persistent Chat ChannelService.exe high CPU

Twice in the last two weeks, I have seen an SfB Persistent Chat server go bonkers over a topology publish action.  Specifically, it would seem that the topology publish action caused channelservice.exe to peg the CPU at 100% with the predictable result of a very sluggish server.

Tangential input and possibly related data points:

The fix was easy enough, in one case I did a stop-cswindowsservice followed by start-cswindowsservice.  In the other case I had to boot the box because PowerShell opened but never responded to any input.

Such is life.

YMMV
