Out of space when running SplitNCigarReads

I know this question has been asked before. I have read the answers of previous post and did fix by the instructions, but this problem keeping occur. I have checked my storage space, there is enough space indeed. Here is my script:

java -d64 -Xmx32g -Djava.io.tmpdif=/home/RNAseq_SCZ/tmp -jar $GATK -T SplitNCigarReads -R /home/hg19seq/hg19.fa -I dedupped.bam -o split.bam -rf ReassignOneMappingQuality -RMQF 255 -RMQT 60 -U ALLOW_N_CIG
AR_READS
