[Ntop] An error occurred while forking ntop

[Kraus, Niki]

Title: Nachricht

Hi,

 

on our small Sun Enterprise 1 Server (Solaris 2.6) I'm running ntop, but I get after lets say 30sec an error when ntop processes want to fork.

Can someone pls. tell me the background or how to overcome this? Here are some specific data regarding the host.

If there are some important parts or configs necessary to analyse the problem pls tell me and I'll provide it asap.

 

The server itself has 128mb ram and a 2.1 gb disk.

If missing swap space could be the reason - it's in normal mode

# swap -l
swapfile             dev  swaplo blocks   free
/dev/md/dsk/d1      85,1      16 262944 123040

 

# df -k
Filesystem            kbytes    used   avail capacity  Mounted on
/dev/md/dsk/d0        288855  226722   33248    88%    /
/dev/md/dsk/d2        288855  166312   93658    64%    /usr

swap                    4008      16    3992     1%    /tmp

 

# which ntop

/usr/local/bin/ntop

 

 

and while running ntop where the error occured I can't even enter some basic commands:

# top
bash: fork: Not enough space

# swap -l
bash: fork: Not enough space

 

Where could I extend a specific limit to run ntop properly?
