Graph creation fails: out of memory error

[Jack Hargett]

Hi,

I'm getting the following error about 4-5 minutes into the graph creation routine:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python2.6/threading.py", line 525, in __bootstrap_inner
    self.run()
  File "fbfriendsgraph.py", line 59, in run
    written = self.graph.write_png(self.filename, prog = 'neato')
  File "/usr/lib/pymodules/python2.6/pydot.py", line 1602, in <lambda>
    lambda path, f=frmt, prog=self.prog : self.write(path, format=f, prog=prog))
  File "/usr/lib/pymodules/python2.6/pydot.py", line 1696, in write
    dot_fd.write(self.create(prog, format))
  File "/usr/lib/pymodules/python2.6/pydot.py", line 1796, in create
    status, stderr_output) )
InvocationException: Program terminated with status: -11. stderr follows: neato: failure to create cairo surface: out of memory

I'm running ubuntu 9.10 (32-bit), AMD Athlon 64 (4000), 3GB RAM, and plenty of free disk / swap.

Any help is greatly appreciated!

Regards,
Jack

Thanks for taking the time to report the bug. However, AFAIK this issue is purely dependent on your machine specs and the complexity of your graph. I have ~300 friends and the graph generation does cripple down my 2 GB RAM/1.8 C2D processor. I'm pretty sure 500+ friends would not work in my case either. For the time being, I'm marking the bug as invalid. However if you think you have a reasonable (technically speaking, nothing to do with social interpretation ;) ) number of friends, feel free to reopen.

Hi there... I just downloaded the lasted release, and the issue I
reported no longer exists! I have successfully generated graphs with
this release, where as I could not with the prior release. I'm not sure
what changes were coded, but just wanted to let you know this issue no
longer exists for me.

Thank you!

Jack

~300 friends, 4 gb ram, 2.53 C2D processor, same error as above with last revision. Should this be reopened?

Which version of graphviz are you using?

[kanor (kanor)]

same error here, 373 friends 24 (!!!) gb memory
graphviz 2.20.2-8ubuntu3
10.04

[Rafał (raafal)]

same error, 358 friends, 6 GB memory
graphviz 2.26.3-4
10.10

[Philipp Zöchner (zornp)]

got the exact same error with < 300 friends.
4 GB RAM
using the latest version from the branch. 4th revision.
11.04 beta

[Philipp Zöchner (zornp)]

my bad.. the last line differs!

InvocationException: Program terminated with status: -11. stderr follows: neato: graph is too large for cairo-renderer bitmaps. Scaling by 0.607089 to fit
neato: failure to create cairo surface: out of memory
