https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=293382 --- Comment #30 from Paul <devgs@ukr.net> --- Thank you for a prompt reply! We are definitely not tampering with the core dump. And only using the HEAD + patch. No custom kernel modules, nothing like that. Curiously, may be just a coincidence, but I've noticed that 544408 - 138904 = 405504, which is a multiple of 4096. Specifically 99 * 4096. Could it be that this is due to some hash-table optimization and them ending up in the same bucket? This may explain why seemingly unrelated fds end up colliding somehow. Though, may just be a coincidence. And 4096 seems a plausible 'magick number' to be used somewhere. Like in a simplified hash function (remainder of division) or just a result of an exponential HT growth with a factor of 2. Regardless, we are now switching to HEAD with only the latest patch which you provided. Thanks! -- You are receiving this mail because: You are the assignee for the bug.home | help
