Orien is correct, it is the fork() system call triggered by ProcessBuilder or Runtime.exec or other means of the JVM executing an external process (e.g. another JVM running ant, a git command, etc.).

There have been some posts on the Jenkins mailing lists about this: Cannot run program "git" ... error=12, Cannot allocate memory

There is a nice description of the issue on the SCons dev list: fork()+exec() vs posix_spawn()

There is a long standing JVM bug report with solutions: Use posix_spawn, not fork, on S10 to avoid swap exhaustion. But I'm not sure if this actually made it into JDK7 as the comments suggest was the plan.

In summary, on Unix-like systems, when one process (e.g. the JVM) needs to launch another process (e.g. git) a system call is made to

Requirements

• no upfront installation/agents on remote/slave machines - ssh should be enough
• application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
• configuration templating
• environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
• deployment process run from Jenkins

Solution

### WordRectangle.py
### Python solution to Cracking the Coding Interview's question 17.25
### Noah Nelson
###
### The problem:
### Given a dictionary or list of words, return the largest rectangle you can
### form out of those words where every row and every column is a valid word.
### All of the rows have to have the same length, and all of the columns,
### but the width and height may be different. The largest rectangle is the
### one with the largest area.

Colours in terminal

It's a common confusion about terminal colours... Actually we have this:

• plain ascii
• ansi escape codes (16 colour codes with bold/italic and background)
• 256 colour palette (216 colours + 16 ansi + 24 gray) (colors are 24bit)
• 24bit true colour ("888" colours (aka 16 milion))
