You might have a look in the sar output if your system uses sar - which may or may not be the case.

Otherwise, you might have some performance monitoring tool running and might find information in its output.

Otherwise, i suppose you are out of luck: you can see the current swapping - quite detailedly so - in the vmstat output, but the figures from yesterday are not there (and to my knowledge anywhere saved). In this case you might set up something - log vmstat to a file, start sar, etc.. - and wait until the problem occurs again.

I hope this helps.

NAME

       libglpk-java - GNU Linear Programming Kit Java Binding

DESCRIPTION

       The  GNU  Linear  Programming  Kit  (GLPK)  package supplies a solver for large scale linear programming (LP) and mixed integer programming
       (MIP).  The GLPK project is hosted at http://www.gnu.org/software/glpk.

       It has two mailing lists:
       - help-glpk@gnu.org and
       - bug-glpk@gnu.org.

       To subscribe to one of these lists, please, send an empty mail with a Subject: header line of just "subscribe" to the list.

       GLPK provides a library written in C and a standalone solver.  The source code provided at ftp://gnu.ftp.org/gnu/glpk/ contains	the  docu-
       mentation of the library in file doc/glpk.pdf.

       The Java platform provides the Java Native Interface (JNI) to integrate non-Java language libraries into Java applications.

       Project GLPK for Java delivers a Java Binding for GLPK. It is hosted at http://glpk-java.sourceforge.net/.

       To report problems and suggestions concerning GLPK for Java, please, send an email to the author at xypron.glpk@gmx.de.

ARCHITECTURE

       A GLPK for Java application will consist of the following
       - the GLPK library
       - the GLPK for Java JNI library
       - the GLPK for Java class library
       - the application code.

GLPK LIBRARY

       The GLPK library can be compiled from source code. Follow the instructions in file INSTALL provided in the source distribution. Precompiled
       packages are available in many Linux distributions.

       The usual installation path for the library is /usr/local/lib/libglpk.so.  The library has to be in the search path for binaries.

GLPK FOR JAVA JNI LIBRARY

       The GLPK for Java JNI library can be compiled from source code. Follow the instructions in file INSTALL provided in  the  source  distribu-
       tion.

       The  usual installation path for the library is /usr/local/lib/jni/libglpk-java.so.  The library has to be in the search path for binaries.
       Specify the library path upon invocation of the application, e.g.
       java -Djava.library.path=/usr/local/libjni

GLPK FOR JAVA CLASS LIBRARY

       The source code to compile the GLPK for Java class library is provided at http://glpk-java.sourceforge.net.

       The GLPK for Java class library can be compiled from source code. Follow the instructions in file INSTALL provided in the source  distribu-
       tion.  The usual installation path for the library is /usr/local/share/java/glpk-java.jar.

       The library has to be in the CLASSPATH. Specify the classpath upon invocation of the application, e.g.
       java -classpath /usr/local/share/java/glpk-java.jar;.

SEE ALSO

       Further documentation and examples can be found in the documentation path, which defaults to /usr/local/share/doc/libglpk-java.
