Один раз запуск программы приводит к 10 экземплярам

У меня есть старый сервер SUSE 8.1, который совсем недавно начал безумие.

Если я запускаю программу один раз:

/usr/local/jdk1.6.0_21/bin/java -cp example-ser-0.8.jar:/usr/local/lib/java/slf4j-api-1.6.1.jar:/usr/local/lib/java/logback-core-0.9.24.jar:/usr/local/lib/java/logback-classic-0.9.24.jar:/usr/local/lib/java/jcl-over-slf4j-1.6.1.jar:/usr/local/lib/java/commons-cli-1.2.jar:/usr/local/lib/java/commons-lang-2.5.jar:/usr/local/lib/java/mysql-connector-java-5.1.13-bin.jar:/usr/local/lib/java/xBaseJ-20091203.jar:/usr/local/lib/java/Translator-0.7.0.jar:/usr/local/lib/java/antlr-3.2.jar:/usr/local/lib/java/joda-time-1.6.jar -Dlogback.configurationFile=logback-test.xml example.ser.Scanner abc12345

Будет запущено 10 экземпляров (тот же пользователь, те же аргументы), как показано ps ax -l | grep Scanner:

Если я ^C терминал, на котором я запустил программу, все 10 исчезают. Эта программа не выполняет никаких разветвлений и не создает дополнительных потоков. Я также пробовал несколько более старых версий этой программы, созданных за много лет до этой проблемы, и все они тоже испытывают это. Что здесь может происходить?
