Howdy, In recent weeks I have noticed a number of clients entering seemingly endless loops writing the cyrus.index on a sometimes empty mailbox, resulting in several dozen MB/s writing to our mail spool for hours on end. Always IMAP, never POP, sometimes TCP/143, mostly TCP/995 I enabled telemetry logging on several of these accounts and here's a typical snippet : <1444726821<1<1444726821<804.3507 IDLE >1444726821>+ idling <1444726821<D<1444726821<ONE >1444726821>1804.3507 OK Completed <1444726821<1<1444726821<805.3507 EXPUNGE >1444726821>* 0 EXISTS * 0 RECENT 1805.3507 OK Completed <1444726821<1<1444726821<806.3507 IDLE >1444726821>+ idling <1444726821<D<1444726821<ONE >1444726821>1806.3507 OK Completed <1444726821<1<1444726821<807.3507 EXPUNGE >1444726822>* 0 EXISTS * 0 RECENT 1807.3507 OK Completed <1444726822<1<1444726822<808.3507 IDLE >1444726822>+ idling <1444726822<D<1444726822<ONE >1444726822>1808.3507 OK Completed <1444726822<1<1444726822<809.3507 EXPUNGE >1444726918>* 0 EXISTS * 0 RECENT 1809.3507 OK Completed Clues ?
