Zeeb --- (In reply to Kristof Provost from comment #20) Well, there is your problem. In the old days we did use locks for exclusiv= ity; that probably has changed on the interface lists, etc. with epoch(). Hen= ce are now having two operations running in parallel and not waiting for each other. At least that sounds very likely to me. I can go and have a look = in about 2 weeks to debug and fix this. --=20 You are receiving this mail because: You are the assignee for the bug.=
