been having this issue for about a month now, unsure what's causing this issue... a reboot usually fixed things, but now it's ever so annoying... i've attached a few links to some logs, sorry too large to post here. my /var/log/syslog my /var/log/messages my /var/log/mail.err my /var/log/mail.info sample ps aux so what happens, is, i have an external monitoring subscription that watches my cloud server for downtime, and when it hits, i'll ssh in and see what's going on.. when I get in, sometimes I can't do anything because program has fork: Cannot allocate memory / too many files open (something similar). when i do a ps aux, i do find that my machine is flooded with tons of smtp processes and error processes... a few sites say adding swap would be beneficial, but in my instance, i can't due to my server being a cloud server and the host does not allow it. any tips will be great. thank you
