System.OutOfMemoryException

Jag har nyligen fått detta error ifrån en site jag har byggt för ett tag sedan.
Den har rullat på hyffsat bra, inga andra error hitintills.

Exception of type 'System.OutOfMemoryException' was thrown.
Description: An unhandled exception occurred during the execution of the 
current web request. Please review the stack trace for more information 
about the error and where it originated in the code.

Lite svårt att veta vad som har gått fel, utan att se någon kod. Har du någon struktur som hanterar mycket data? Läser du in stora datamängder från någon annan källa (fil, databas, annan I/O)? Opererar du på denna data på ett minnes-ineffektivt sätt? Svårt att säga, men nu har du lite uppslag... ;)

Försök att lokalisera felet genom att plocka bort delar av kod som du tror skulle kunna ge upphov till problemet. (Om du nu har möjlighet till det)

Jo men det märkvärdiga är att det har fungerat kanonbra, och helt plötsligt så kom det här.

Tydligen så var det någonting hos webbhotellet för nu fungerar det igen :-)
