[rt-users] RT and mail loops

[Byron Jones]

hello again,

background: viewing a number of tickets results in 100% cpu, 100% memory
usage, dead server.
to the point where there's a script that runs every minute killing
runaway httpd processes.


the problem we're experiencing is because the tickets have a LARGE
number of transactions, due to a mail loop.

example:

  SELECT COUNT(id) FROM Transactions WHERE ObjectId=30514
  = 1,186

  then doing a
  SELECT COUNT(id) FROM Attachments WHERE TransactionId=?
  for each of the entries in the Transactions table
  = 169,328
  
little wonder it hurt the server.


does RT have any built-in mail-loop detection?


is it possible to set a hard limit on the number of transactions that
can be added to a ticket?
for our RT install i wouldn't see any problems setting this limit to
1,000 transactions


is it possible for a future version of RT to implement paging for
viewing ticket transactions?
for example, only show 100 transactions per page, with a "next page"
button or similar navigation.




thanks,

byron
