mysql error: Can't create/write to file '/tmp/#sql1153_4c5cc_4.MYD' (Errcode: 23)

mysql error number: 1

Looks like your MySQL cannot write to that, error 23 means too many files are open and 1 is Operation not permitted

so how do i find out why 2 many files are open and fix this problem.Its gone away now but it may come back.

Your system was problay overloaded at that point in time,

seems everything was - ftp went down - email went down (im on virtual hosting) and sent email to host but they say everything is fine when it clearly aint as i get weird errors going into my c-panel so the problem has to lie with them.
