i'm wondering of anybody here could help me out with a #openbsd networking issue?
on my server i am having this weird issue of TCP handshakes randomly failing, but after the handshake completes the connection is completely fine. i dont think its a pf issue as it happens with it both enabled and disabled
it started around 48-hours again and i didnt touch any configuration files during that time
it happens with my IRC bouncer,HTTP(S),and FTP server, with/without TLS

omg i think i just found the issue, postgresql was taking nearly 99% of the semaphore allocated to the system and the kernel for some weird reason freaking out about it and dropping packets.... anyways, for anyone in the future with this issue just add these two lines to your sysctl.conf ``` kern.seminfo.semmns=4096 kern.seminfo.semmni=4096 ``` thank you to everyone who was trying to help ^__^
