Could somebody explain what this error means?

What is ip, sp and what does the numbers stand for?

If I grep -i "general protection ip" messages* I get below output. It is happening quite often and we need to restart php, db2 etc to make things work again. Not sure if below is related to it but we need to investiga it too.

It means PHP crashed.

Visit PHP's bugs page for more information on determining why it crashed, and how to report the bug (if it wasn't already reported and/or fixed).

  • I cannot see anywhere what the numbers mean. Is it let's say memory address? It would be helpful to know.

  • ip: instruction pointer sp: stack pointer. It's telling you where it was when it crashed. to answer your question 5 years later :)
