Jan Lindström (Inactive) added a comment - 2020-04-09 17:18 If problem does not repeat WITH_WSREP=OFF it is just matter of grepping WITH_WSREP and finding the offending code by e.g. changing WITH_WSREP with WITH_WSREP_DISABLED until the problem part if found.

Julius Goryavsky added a comment - 2020-05-12 11:47 A thorough check was performed both manually and with a modified version of mtr (which does not change "ulimit -n" in safe_processs.cc) - the problem is not confirmed at the moment, the number of open files is the same both when building with wsrep or without. There are very insignificant differences in the operations of writing to files, which are explained by the innodb code in connection with some additions specific to wsrep, but the number of open files remains the same.

Oleksandr Byelkin added a comment - 2020-05-19 08:38 OK, I will recheck

Oleksandr Byelkin added a comment - 2020-05-19 10:54 Yes it looks like it gone
