The last working build is from June 4th a= nd it was probably 92f49c769b4e. Problem description: The database client (mysql/mariadb) running in the jail is no more able to access the database over the network socket on the host (mysql/mariadb) nei= ther on the 127.0.0.1 address nor on the shred interface address (10.x.x.x). It = is classic jail, not VNET jail. Switching to net.inet.tcp.functions_default=3Dfreebsd solves the issue. The problem occu= rs irregardless of the used net.inet.tcp.cc.algorithm (tested with htcp and newreno). Conclusion: Testing RACK on FreeBSD is becoming really hard task. Switching to default net.inet.tcp.functions_default=3Dfreebsd solves a lot of issues and reduces= the PR submitting ratio. --=20 You are receiving this mail because: You are the assignee for the bug.=
