problem with rrdtool 1.2.11

[disorganizer]

i got a problem getting rrdtool 1.2.11 to run with my cacti and cactid (all patches installed, all other sw version as of monday this week).
rrdtool was downloaded from cacti-site today.

when i go from 1.2.10 to 1.2.11, no rra's are generated by poller.php.
going back to 1.2.10 immediately gets me the rra's without any other change to the system.

so i checked the debug output of poller.php...
all looked fine, both versions get exactly the same output.

so i extracted the rrdtool-call out of the log and tried it manually on the rrdtool 1.2.11... and it worked immediately without any error.
also graph generation works with the new version (much faster).


any idea on that one?
anything else to look at?

Did the call include the "-" sign right after it's inception?

here is the call in the logfile:

was that helpful?
i hope so. as you see the calls are identical, as said the strange thing is that if i copy+paste the above calls to the cmd-prompt in windows it works.

If you could run both from the command line and post the output, I would greatly appreciate it.

that is easy. the output is.... none... in both cases *sigh*.

i am now trying to run poller.php with php.exe and create some output.


and.... voila!!! (strangely you only see this when running poller.php with php.exe poller.php >somefile.txt, not on screen!).

Code: Select all

E:\cactid\cactid.exe (6104): *** system shared memory version mismatch detected
- 0x75BE0084/0x75BE0081.
This problem is probably due to using incompatible versions of the cygwin DLL.
Search for cygwin1.dll using the Windows Start->Find/Search facility
and delete all but the most recent version.  The most recent version *should*
reside in x:\cygwin\bin, where 'x' is the drive on which you have
installed the cygwin distribution.  Rebooting is also suggested if you
are unable to find another cygwin DLL.

obviously the wrong cygwin.dll is packed with rrdtool.exe in the download?

second strange thing is: why is it working when used from command-prompt?!?


i will now try a reboot to see if it corrects my problem (i knew it had something to do with windows *g*)


EDIT:
i found something else after the reboot didnt work.
cactid comes with a cygwin1.dll. and there was the version conflict.
after exchanging the cygwin1.dll of cactid with the one delivered with rrdtool.exe i had no error message. let me wait a few hours to see whether data is collected.....

[disorganizer]

it worked!

exchanging the cygwin dll of cactid with the one delivered with rrdtool 1.2.11 was definitely the solution.


and as always, the solution could have been clear from the beginning *g*
cactid uses cygwin and calls rrdtool.
as windows does not seperate the memory clearly between running applications, rrdtool then tries to call cygwin in a different version than in which it is in memory.

disorganizer,

You don't have it 100% correct as Cactid does not call rrdtool. But thats Ok. Glad you found the problem.
