lsof gives "information error: Cannot allocate memory" in iOS

Question

My intent is to check for TCP and UDP being opened by a specific process.

lsof -p $1 | grep -E "TCP|UDP" (this works well on Mac OS)

I installed lsof binary on a jailbroken iPad, from cydia. When i execute lsof on iOS device (terminal), it just gives me errors saying: information error: Cannot allocate memory

I tried compiling lsof for iOS (arm) from various sources but the make fails.

Also tried to install .deb on the iPad, using dpkg -i but it gave errors saying that ruby and other dependencies are not found.

Would be great if I could get help in getting lsof to function properly on iOS. Or a working alternative for lsof. Thanks.

update

I copy the file from my old device and upload it to GitHub here.

I encounter the same problem. I solved it by this:

1. Download lsof-arm7-iOS4.2.
2. Backup the old lsof to lsof-backup.
3. Copy the downloaded the lsof-arm7-iOS4.2 to iDevice.
4. Rename the lsof-arm7-iOS4.2 to lsof
5. Then chmod +x lsof
