@Jdforrester-WMF noticed that logspam is attempting to tail fatal.log, which doesn't exist. Per @Krinkle, this shouldn't be necessary any more:
11:51 <Krinkle> James_F: right, there's virtually nothing left using that channel. except maybe a week-old app server that hasn't had a scap deploy 11:51 <Krinkle> it's all exception.log now 11:55 <brennen> Krinkle: yeah - in that case, should i remove fatal.log watching altogether? 11:55 <Krinkle> brennen: yes 11:55 <brennen> kk 11:55 <Krinkle> keep old log files but any references to it are fine to remove
