Re: [Cppcms-users] 100% cpu usage

[Artyom B. <art...@ya...>]

Guys

To try to figure out what happens I really need a test case that reproduces the problem
to see what happens, or somebody would join the process that uses 100% CPU with a debugger
and bring some stack trace and see what is the loop that happens there

Without it I can't tell what is the problem. It also may be incorrect use of API. I had already 
seen some problems that were reported that actually was API abuse. It is especially gentle
in case of multi-threading and asynchronous programming.

No, I hadn't tried it yet.

Yo.

Both for me too, but only the app is c++11, not cppcms itself.

Hmm. 10s is much too less and it does not happen every time.

Would be great if you can trigger that problem and know what it causes.

Get your SQL database under version control now!
Version control is standard for application code, but databases havent 
caught up. So what steps can you take to put your SQL databases under 
version control? Why should you start doing it? Read more to find out. http://pubads.g.doubleclick.net/gampad/clk?id=49501711&iu=/4140/ostg.clktrk
